Edit Transitions In State Lifeline

A Timing diagram allows you to show the transitions (changes of state) that occur within a state machine over a fixed time period and at certain timing points. This is similar in many respects to an Interaction lifeline with State changes highlighted. As events and changes occur within the instance this Timing diagram represents, state changes occur and are mapped onto this Timeline. In that respect it is a record of how a particular aspect of the system behaves over time.

When building a Timeline it is necessary to define the States first - and then to add the explicit transitions between those states at particular timing points.

After you have added states, you can add transitions between states directly on the timeline using the mouse.
